The social web weekly: a quick-fire roundup of some of the news, announcements and conversations that have occurred throughout the week…

MySpace still leading Facebook for U.S. traffic. Not surprising to me, but Hiwise has released stats on social networking site visits in the U.S. The short of it is: MySpace still dominates, although Facebook is growing steadily (as is the sector as a whole). Marshall Kirkpratrick (over at RWW) has some good analysis: "It appears that social networking has grown in general; though Facebook posts impressive numbers of new users, in terms of sheer visits Myspace is nearly keeping up with its growth."

Yahoo announces support for OpenID 2.0. This one is being hailed as a big deal in the blogosphere, and in some ways it is. Yahoo says that it plans to support the OpenID 2.0 single sign-on framework and, as Larry Dignan writes: "bring its 248 million users to the Web’s interoperability party." This means that anybody with a Yahoo account will be able to use those log-in details to sign-in to other sites which support OpenID. One more step towards eradicating social networking fatigue. At the risk of pouring cold water on the news: Yahoo's support is one-way: you'll be able to use your Yahoo account to sign-in to other OpenID supporting sites, but you won't (yet) be able to sign into Yahoo with an OpenID account created elsewhere. Secondly, OpenID isn't without its potential security issues.

Digg Reel launches. The online video network, Revision3, have launched their second Digg-inspired show called Digg Reel. Presented by Jessica Corbin, the new show highlights the top videos submitted each week to the social news site. Revision3 already produces Diggnation, a show which, similarly, discusses the top user-submitted stories on Digg. The connection doesn't stop there: both Digg and Revision3 were founded by Kevin Rose and Jay Adelman. However, the interesting part, aside from creating two video shows off the back of user submitted content (crowdsourced television pre-production?), is that, unlike Diggnation, Digg Reel will likely step on a few copyright land mines. The majority of content submitted to Digg is copyrighted (much originating from television), and Digg Reel is republishing those clips (unlike Digg which is just linking to them) and so will need to clear copyright first, if it is to stay on the right side of the law.
